Triangulum II
(Tri II, Laevens 2)
(dwarf galaxy in the Local Group)
Triangulum II (Tri II or Laevens 2) is
a dwarf galaxy of about 1000 stars, an ultra-faint dwarf galaxy (UFD)
roughly 30 kpc from the center of the Milky Way,
discovered in 2015 within the constellation, Triangulum.
It was determined to have a very high mass considering its small
star count, but a subsequent determination suggests its mass
isn't so high.
